if you read his thread he's new to tiling so i would say he should go with 2 days at steady pace (speed comes with experience)
turtle tiling - use HARDI BACKER BOARDS from topps,screw it down every 300mm inch half screws,then you can tile straight onto it, (the boards are concrete dipped) then use flexi rapid set adhesive ! go in with a quote £180 for the 2 days!
good luck!
